The quality of guitars built by Kasuga was very good. Legend has it that the Japanese workshop used pre-machined materials that were made in the USA by Guild.
There doesn’t seem to be a consensus regarding those assembled in Korea—maybe some used materials from the US, maybe not.
For instance: Definitive historical information about Madeira by Guild is scarce.
Less seen—on the steel string acoustics—is the double raised top.
All early Japanese guitars have the flat-topped headstock.
To capture a share of the budget market, many American manufacturers have a separate, more affordable line of guitars.
Since production of these guitars is offshore, where labor is cheaper, they are sometimes referred to as import-lines.
The first generation had a Martin Style headstock with a flat top.
The second generation featured a rounded or curved top.Often times they are an incredible bang for the buck.The quality depends on who you ask, model series, country of origin and how much it was worn down, cared for, or upgraded.“They all had one thing in common though: they sucked.You can narrow down the age of an acoustic steel string by looking at the headstock.There are at least three basic headstock designs on Madeira steel string acoustics.Speculations abound that assembly moved from Japan to Korea in the 1980’s.
